Abstract

A method for dynamic packet retransmissions of a radio link control, hereinafter called RLC, layer for an RLC entity of a transmitter in a wireless communications system is disclosed and includes the following steps. A first RLC packet, including a first header and a first data field, is transmitted to a receiver (402). A negative acknowledgment signal corresponding to the first RLC packet is received from the receiver (404). A first TB size is indicated and received from a protocol layer lower than the RLC layer (406). A second RLC packet is constructed, whose size depends on the first TB size, includes a second header and a second data field including a portion of the first data field (408). The second RLC packet is then transmitted to the receiver (416).
